. bearing brackets 3 and 4:, the bracket 3 having a vertical extension 5 while a pair of. cars 6 rise from the bearing 4. Also extending vertically from a portion of the bearing 3 between the extension 5 and the ears 6 is a post 7 whose upper end is forked at S and constitutes a horizontal guide, one side of the fork having a vertical slot 9 for a purpose to appear.

An upright stub shaft 10 is secured by a set screw or the like 11 in the extension 5 of bearing 3, a horizontally disposed feed wheel 12 being mounted rotatably on said shaft and held in operative position thereon by means of a screw 13 whose head is'received in a cavity 14 in said wheel, said screw being threaded into the upper end of the stub'shaft 10. A beveled pinion 15 is formed integrally with the lower side of the feed wheel 12, said pinion being in mesh with a beveled gear 16 secured on one end of a longitudinally disposed operating shaft 17 which is rotatably mounted in the bearings 3 and 1. Any preferred means may be provided for driving the shaft 17, but a fly wheel 18 is preferably secured to one end thereof, said wheel having a peripheral groove 19 for the reception of a driven belt if the machine is to be operated by power, but having a crank 20 whereby it may be actuated byhand. I

The upper side of the feed wheel 12 at the edge thereof is provided with teeth 21 adapted to engage a shoe sole when the latter is being operated uponby the machine as shown in Fig. 9, said upper side of the wheel 12 also having an upstanding annular shoulder 22 which is adapted to engage the edge of the shoe sole to effectively guide the A pressing lever 23 passes slidably through the fork S and is provided at one end with a horizontal slot 24, this end of the lever being received between the ears 6 in which position it is retained by a pin 25 vpassing 100 through said ears and through said. slot. The other end of the lever 23 is disposed above the feed wheel 12 and carries a channeling knife 26 and a bracket 27, which latter controls the depth of the cut made by 105 the knife. The lever 23 is normally depressed by the tension of a coiled spring 28 which forces downwardly upon a stop 29 on the lower end of an upright rod 30, the

upper end of said rod being pivoted at 31 110 to the aforesaid lever. j As shown most clearly in Fig. 3, the lower end of the rod 30 and the spring 28 are received in the hollow standard 1.

\Vhenit is necessary to raise the free end of the lever 23 to permit the insertion and removal of shoe soles, a hand lever 32 will be depressed, said lever being fulcrumed between its ends on the shaft 17 between the bearings 3 and 4. One end of the lever32 is bifurcated at 33 for the reception of the rod 31, the furcations of this end of the' to be described. A rectangular block 36 is mounted slidablv but non-rotatably in the slot 9 of fork s," saidblock having formed horizontally therethrough a circular bore 37. The bore 37 receives therein a cylindrical block '38 through which an eccentric bore 39 extends. A clamping screw 40 passes through bore 39 and is threaded into the lever 23, the outer end of said screw being squared at 41 for the reception of a key 42 (see dotted lines in Fig. 3) and said end of this screw 40 has formed thereon an outstanding flange 43 which is adapted to be forced into frictional engagement with the outer end of the cylindrical block 38 when the screw is tightened, thereby normally holding said block against rotation. The block 38 however, is formed with radial sockets 44 opening through its periphery as shown most clearly in Figs. 3 and 8, said sockets being adapted for engagement by a spanner wrench'or the like when screw 40 is loosened. It will thus be evident that the block 38 constitutes an eccentric which when properly turned will adjust the screw 40 horizontally, the'lever 23 moving with said! screw. During this operation, said lever 23 will neither be raised nor lowered due to the fact that the block 36 will slide vertically "within the slot 9. As lever 23 moves horizontally, the rod 30 may yield but the opening 45 in the standard 1 through. which said amount. I

rod passes is preferably made sufficiently large to allow said rod to cant the necessary The knife 26 above referred to may be of any suitable construction but is preferably shaped approximately as shown in Fig. 5, said knife having an attaching plate 46 which is secured by set screws 47 to aflange 48 formed integrally with and depending By mounting from the lever 23. As heretofore stated, the distance which the 'l-inlfe 2G penetrates thepreferably ,though not necessarily cast, said bracket being "arched as shown clearly in r 1 Figs. 4, 6 and 7 with its legs 49 and 50 disposed in sliding contact with the front and rear sides of the free end of thelever the leg 50 being greater in length than 49 3 and extending a considerable distance below said end of the lever. The lower end of said arm 50 is bifurcated, the furcations thereof receiving therebetween a sole engaging shoe 52 which is preferably in the form of a roller as shown. The upper end or top plate.53 of bracket 27 has forn'ied therein a slot 54 which receives the intermediate por-' tion of an upright adjusting screw which is threaded into the free end of the lever said screw having collars above and below said plate 53 whereby as said screw is turned by the key'42 or by other suitable means, the entire bracket 27 will. be adjusted vertically to raise or lower the shoe thereby allow ing the knife 26 to penetrate a greater r less amount into the shoe sole, said shoeing engaging the shoe sole as shown in Fig. 9. For locking the bracket 27 in. its vertically adjusted position, the leg 50 thereof will preferably be provided with an opening 5'? through which a clamping screw 58 passes loosely, said screw having a squared outer end equipped with a flange 59 to engage the leg 50 when said screw is tightened, the

inner end of the latter being threaded into the lever 23 as shownin Fig. 4.

The operation of the improved machine is as follows :The shoe sole whether independent of or attached to an upper disposed in the machine as shown in Fig. 5-), this being allowed by first raising the lever 23 through the instrumentality of the hand lever 32. Said lever 23 is now adjusted horizontallyto position the knife 26 the desired distance from the edge of the sole and the bracket 27 is likewise adjusted to allow said knife to penetrate the sole the necessary amount. These adjustments having been made, the shaft 17 will be rotated with the result that the gear and pinion l6 and 15 respectively will rotate the feed wheel 12, the latter now advancing the sole of the shoe against the knife-which cuts therein a channel to receive the usual stitches by means of which the sole is secured to the projecting welt of the shoe. During the channeling operation, if the welt be sufficiently wide, the edge of the sole will engage the shoulder 22 which will serve as a gage to cause the channel to be spaced eqni-distantly from said edge throughout its length. However, when channeling more finely constructed shoes, the

with the accompanying drawing, the construction, manner of operation and advantages of the improved machine will be readily understood without requiring a more extended explanation; In conclusion, however, I will'state that although I have shown and describedcertain details of construction for accomplishing probably the best results, numerous changes may be made Within the scope of the invention as claimed without sacrificingthe main advantages thereof. I claim: 1. In a sole channeling machine, the combination of a horizontally disposed feed wheel upon whose upper side at one edge thereof a shoe sole is adapted to rest, said side of the wheel having an upstanding annular shoulder concentric with its peri hery to engage the edge of the sole and gui e the ing end, an arched latter, means for driving said feed wheel, and a sole channeling knife above, the aforesaid edge of said wheel. r
